I like to joke around when I am working. I understand that it's not everyone's cup of tea, but ffs you should be able to laugh at really complex problems in stressful situations. How else can you remain sane writing thousands of lines of code just for an e-commerce site or so someone can post even more cat pictures on the Internet.

If you can't laugh and enjoy what you are doing, you might want to rethink what you are doing with your life.
